Using fractal model in documents' security

Abstract EN

The research aims to build graphical models of complex formation and morphology which can be used to secure paper documents from attempts of fraud, especially those trying to expose them to scanning.

Therefore, the scanned version will differ in features from the original one, particularly the part that contains the seal (the decorative form).

The forms were generated by using a model of Koch's star ; keeping in mind that points of the lines of the new form will be generated by using Brsenham's theory in order to generate the straight line.
